Testing will begin in July, pending weather or unforeseen circumstances, and will continue through the end of September.

Smoke testing is a way to locate openings in the sewer system that allow rainwater runoff to enter and cause expensive sewer backups. To conduct a smoke test, air is combined with non-toxic smoke and forced into sewer lines to reveal the location of leaks and connections to storm water systems. If there are defects in the lines, smoke can be seen coming out of the ground at the location of the defect.

Residents in the testing areas should expect work to occur through the end of September. Smoke will not enter buildings unless there is defective plumbing or drain traps that have dried up; it is normal for smoke to come out of the sewer vent stack on the roof of a home during the test. However, if smoke is observed inside the home during the test, residents should call the Water Department immediately at 972-205-3200.

The smoke used for testing is non-toxic, creates no fire hazard, leaves no residue, dissipates quickly, and is harmless. However, those with respiratory issues may wish to take extra precautions such as leaving the home for a few hours until testing is complete. Door hanger notification cards will be distributed in the testing areas immediately prior to testing.
